How did JavaScript start?

1. Creation in Netscape

JavaScript was created in 1995 by Brendan Eich while he was working at Netscape Communications, the company behind the Netscape Navigator browser, one of the first popular web browsers . Netscape wanted to add a scripting language to its browser to allow web developers to add interactivity to web pages.

2. Development in 10 days

Brendan Eich developed the language in just 10 days. It was originally called Mocha, but the name changed first to LiveScript and then finally to JavaScript to take advantage of the popularity of the Java language at that time. moment, even though JavaScript and Java are completely different languages.

3. Competition with Microsoft

In the 1990s, Netscape's main competitor was Microsoft, which in response to the popularity of JavaScript developed its own version of the language called JScript, which was integrated into its browser, Internet Explorer. This competition caused a fragmentation in the way browsers handled JavaScript, making it difficult for developers to write code that worked consistently across browsers.

4. ECMAScript standard

To resolve the fragmentation, Netscape submitted JavaScript to ECMA International (European Computer Manufacturers Association) to standardize the language. In 1997, the first standard was published, known as ECMAScript (abbreviated ES). From then on, the official versions of the JavaScript language have followed the ECMAScript standard, which continues to evolve to this day.

5. The Rise of Ajax

In the 2000s, JavaScript became even more important with the introduction of Ajax (Asynchronous JavaScript and XML), a technique that allowed web applications to update content without reloading the page. This marked the beginning of dynamic web applications and paved the way for the development of more interactive web services such as Gmail and Google Maps.

6. The Node.js Revolution

In 2009, Ryan Dahl released Node.js, a runtime environment that allowed JavaScript to be run on the server. This marked a significant change, as it allowed developers to use the same language on both the frontend and backend, furthering the rise of JavaScript as a general-purpose language. .

7. Frameworks and Modern Libraries

Throughout the 2010s, frameworks and libraries such as Angular, React and Vue.js emerged, making web application development easier. complex. These tools helped cement JavaScript as the core language of modern web development.

8. Current Status

Today, JavaScript is the most popular and dominant language in web development, both on the client side (frontend) and on the server side (backend) thanks to technologies like Node.js. With a vibrant and constantly evolving ecosystem, it remains essential for web and mobile application development.

Conclusion

JavaScript started out as a language developed quickly to add interactivity to browsers, but it has grown enormously since then, becoming a key piece of the modern web. Its history reflects its ability to adapt and evolve, which has allowed it to remain relevant and essential in software development.
